MMAjunkie.com (www.mmajunkie.com) has learned from sources close to the event that Karalexis and “The Mongolian Wolf” have both verbally agreed to the WEC 51 contest, and bout agreements are expected to be finalized shortly.

Featuring a featherweight title fight between current champion Jose Aldo and UFC veteran Manny Gamburyan, WEC 51 takes place Sept. 30 in Broomfield, Colo. The main card airs live on Versus.

Karalexis vs. Quan is expected to serve as a preliminary-card contest.

Karalexis returns to the cage for the first time since a WEC 48 loss to Anthony Pettis. Known for an aggressive, brawling style, Karalexis stood toe-to-toe with the dynamic Pettis before succumbing to a second-round triangle choke.

The bout kicked-off the Spike TV-broadcast portion of the wildly successful pay-per-view event.

Karalexis, a cast member of the original season of “The Ultimate Fighter,” is in need of a win after tasting victory just once in his past four outings.

Meanwhile, Quan fights in the U.S. for the first time.

The undefeated 25-year-old has opened his career with 10-straight stoppage wins, which included victories wins by TKO. Hailing from Inner Mongolia, Quan sports a purple belt in Brazilian jiu jitsu and also wrestled throughout his childhood.

Quan’s most recent outing was a June win via neck crank that took just 30 seconds. The fight took place in China.
